Some pro/cons that would be interesting to discuss:
Other than licensing, an advantage I'm guessing is in reducing noisy neighbor affects. In our case, we use a lot of t2.micro instances, which seem to suffer from this.
A disadvantage is that the instances within a dedicated host might all go down together? (similar to if you put all your instances in us-east-1e and 1e goes down?, or of course if all of us-east goes down). Although I'm not sure a dedicated host itself is more likely to go down, while a datacenter remains operational. That's what I'm most interested in knowing - how do these fail?

- brianwawok 11y agoYou have to consider it a SPOF. Put nothing on the same dedicated host that you cannot fail at the same time. Though in AWS speak, generally you treat an availability zone as a SPOF... so dedicated host is of course a SPOF...
